<h1>Creating a dynamic Heat Map</h1>
<p>For an introduction to the Heat Map widget, see 
<a HREF="Heat_Map_widget.htm">Defining 
 a Heat Map widget</a>.</p>
<p>When you use a Heat Map widget in a document, you can also add a selector 
 to create a dynamic Heat Map. This type of heat map is considered dynamic 
 because a user can use the selector, such as a Drop-down list, to select 
 a different attribute element to be displayed by the heat map.</p>
<h2>To create a dynamic Heat Map</h2>
<ol type="1" class="whs1">
	
<li class=p><p class="whs2">Insert a Heat Map widget into 
 the document. For more information, see 
<a href="Heat_Map_widget.htm">Defining 
 a Heat Map widget</a>.</p></li>
	
<li class=p><p class="whs2">Add at least <span style="font-weight: bold;"><B>one 
 attribute</B></span> to the Grid/Graph's rows and <span style="font-weight: bold;"><B>two 
 metrics</B></span> to the Grid/Graph's columns. </p></li>
	
<li class=p><p class="whs2">Insert a selector, such as 
 a Drop-down list, next to the widget. For steps, see 
<a HREF="Insert_a_selector.htm">Inserting 
 a selector into a document</a>. </p></li>
	
<li class=p><p class="whs2">Choose an attribute from the 
 dataset that is not already in the Grid/Graph and set this attribute as 
 the Source of the selector. Do not include this attribute on the Grid/Graph 
 itself. It is used to populate the selector.</p></li>
	
<li class=p><p class="whs2">Set the Grid\Graph as the 
 target of the selector.</p></li>
</ol>
<p class="whs3">For example, a Grid/Graph (for a Heat Map 
 widget) has Category and Subcategory attributes on its rows and one of 
 the metrics on its columns is the Revenue metric. However, you want to 
 use a selector to see heat maps for categories and subcategories in specific 
 regions. In this case, you create a drop-down selector, set the Region 
 attribute as its Source, and set the Grid/Graph as its Target. The Region 
 attribute should not be added to the Grid/Graph because, if it is, all 
 regions will be displayed on the heat map. In Flash Mode, you can use 
 the selector to choose different regions for which to view category and 
 subcategory data.</p>
